I'm 20 and I've had this phobia since I was 8 years old. It's taken me 12 years to figure out that other people suffer from this too, and that I need to seek help for it. I think that if someone had realized what I was going through earlier and I had started working on this when I was 8, the last 12 years of my life would have been so much more bearable. I would start looking into treatment for your daughter. If she doesn't end up having emet, no harm, no foul, but if she does, getting started early can only be a good thing.
